hi m chasis mentor/masters,

i need some help, well you see i sort quit r/c racing due to dying nimh cells on touring cars, but recently, i discover a whole new world in R/C, something i look at it as a toy before, and now i tested it, it really give great fun, you guess , My M chasis mini rover. thannk to a friend who show me the website rc-mini.net,
which show me how to enjoy R/c with minimal cost,

well start with my question,

1) what the best rubber tyre(long lasting but still able drive agressively on tarmac)?
, i heard the hpi x pattern was the best, but its a bit on the pricy site, my local dirvers use 1/10 foam tyres, cheap but to me i feel it looks ugly on a mini. so i prefer to race them with my stock tamiya rubber with out insert...and maintain mini looking tire size,

2) i recently also moved to lipo, my 1st lipo packs its yeah racing 3200, i have install novak 2 cell smart stop, before running i use a lipo voltage checker to check the lipo voltage, than i tried to run until the lipo smart kick in, but i was terified to find that the voltage on the lipo its 0.0v, i hurried home to and charge my yeah racing lipo, after 5 min charge, the voltage came back to normal. so i dare not ran until the smart stop kick in again, any idea what happen to the lipo cells to show 0.0v? i read somewhere that yeah racing lipo have build in smart stop to prevent overdischarging? is it true? what the best way to get the full out of my lipo?

that all for now, hope to read more here soon......thanks....
